In this post, we’ll dive deep into the many ways you can use purple basil in cooking, covering everything from the best preservation methods to the most delicious pairing ideas.
Let’s get right into the kitchen and explore the magic of this beautiful herb.
How to Use Purple Basil in Cooking: The Core Techniques
The most important thing to remember when you want to use purple basil in cooking is that heat can be its enemy.
Unlike green basil, which can hold up reasonably well when stirred into a hot sauce at the last minute, purple basil tends to lose its striking color quickly when exposed to prolonged high temperatures.
The leaves will turn a dull, muddy green color, and while the flavor will still be lovely, you lose the visual appeal that makes purple basil so special.
However, that doesn’t mean you can’t cook with it; it just means you need to be strategic about when you add it to the pan.
The best way to use purple basil in cooking is to add it at the very end of the cooking process, or better yet, use it fresh as a finishing touch.
Here are the core techniques that will help you get the most out of this stunning herb.
1. Fresh in Salads and as a Garnish
The absolute easiest and most rewarding way to use purple basil in cooking is to skip the cooking altogether.
Toss whole or torn leaves into a fresh green salad, a Caprese salad, or a watermelon and feta salad for a pop of color that’s almost too pretty to eat.
You can also use purple basil in cooking as a final garnish for soups, pasta dishes, pizzas, or grilled meats right before serving.
The vibrant purple leaves contrast beautifully with the other colors on the plate, and the fresh, aromatic quality is unbeatable.
For a simple side dish, sprinkle a handful of shredded purple basil over sliced tomatoes with a drizzle of olive oil and a pinch of sea salt.
2. Infused Vinegars and Oils
One of the smartest ways to use purple basil in cooking is to capture its color and flavor in a liquid form that lasts for weeks.
Making a purple basil-infused vinegar is incredibly simple and yields a beautiful, rosy-pink liquid that’s perfect for salad dressings.
Just gently bruise the leaves, place them in a clean jar, cover with white wine vinegar, and let it sit in a cool, dark place for about two weeks.
Similarly, you can use purple basil in cooking by making a quick garlic and basil oil.
Blanch the leaves briefly in boiling water, shock them in ice water, then puree them with a good quality olive oil and a clove of garlic.
This vibrant oil is incredible drizzled over bruschetta, roasted vegetables, or grilled fish.
3. Pesto with a Purple Twist
Of course, you have to think about pesto when you want to use purple basil in cooking.
This is perhaps one of the most satisfying uses because you get a shockingly beautiful, deep magenta pesto that tastes every bit as good as the traditional green version.
Simply replace the sweet basil in your favorite pesto recipe with purple basil.
You can use purple basil in cooking for a classic Genovese-style pesto with pine nuts, parmesan, garlic, and olive oil, or get creative by swapping the pine nuts for walnuts or almonds.
The pesto is perfect tossed with pasta, spread on sandwiches, or served as a dip with crusty bread.
Ways to Use Purple Basil in Cooking That Preserve Its Beauty
If you really want to use purple basil in cooking with heat, you need to understand how to protect that delicate color.
The key is to minimize cooking time and use techniques that don’t involve boiling or sautéing for long periods.
Here are some specialized ways to use purple basil in cooking that keep it looking fantastic.
1. Steep It in Liquids
Instead of chopping and stirring it into a hot dish, you can use purple basil in cooking to infuse liquids with its essence.
Make a simple syrup by heating water and sugar, then adding a large handful of purple basil leaves and letting them steep off the heat for 30 minutes.
This creates a gorgeous, lavender-hued syrup that is perfect for cocktails, lemonades, or drizzling over fresh fruit.
Similarly, you can steep purple basil leaves in hot cream to make an incredible basil-infused cream sauce.
Strain the leaves out before serving to get the flavor without the color change.
2. Add It at the Last Minute
There is a time and a place for adding purple basil to a hot dish, but you have to be quick about it.
If you’re making a stir-fry or a simple tomato pasta sauce, add the purple basil leaves whole in the final 30 seconds of cooking.
Just toss them in and immediately remove the pan from the heat.
The residual heat will gently wilt the leaves, releasing their aroma, but the exposure will be too brief for them to completely lose their color.
This is a great trick to use with Thai-inspired dishes, where the herb is often added at the end, and you can use purple basil in cooking as a direct substitute for Thai basil.
3. Freezing for Later Use
Preserving purple basil is a fantastic way to use purple basil in cooking all year round.
Blanch the leaves in boiling water for a couple of seconds, then immediately plunge them into an ice bath.
Pat them dry, and then you can lay them flat in a single layer on a baking sheet and freeze them.
Once frozen, you can transfer the leaves to a freezer bag.
They won’t be great for fresh salads after this, but they will still be perfect for use in cooked sauces, soups, and pesto.
Another clever way to use purple basil in cooking for freezing is to chop the leaves and mix them with olive oil in an ice cube tray.
Pop out a cube or two whenever you want to add a burst of basil flavor to a dish.
Recipe Ideas to Showcase How to Use Purple Basil in Cooking
Sometimes all you need is a little inspiration to get going.
So, let’s look at some specific recipe ideas that highlight exactly how to use purple basil in cooking.
1. Purple Basil Lemonade
This is the perfect summer drink and shows off the herb’s natural beauty.
Make a batch of purple basil simple syrup as described above.
Then, in a large pitcher, combine fresh lemon juice, cold water, and the purple syrup to taste.
Add a few whole leaves of purple basil to the pitcher for garnish.
The result is a stunning, pale pink-to-lavender drink that is both refreshing and aromatic.
It’s an excellent example of how to use purple basil in cooking for beverages.
2. Grilled Peach and Purple Basil Salad
Grilled fruits and fresh herbs are a match made in heaven.
Grill halved peaches until they have nice char marks.
Arrange them on a bed of arugula, then top with crumbled goat cheese, toasted pecans, and a generous handful of fresh purple basil leaves.
You can use purple basil in cooking here not as a cooked ingredient but as the star fresh element that ties the sweet, savory, and peppery flavors together.
Drizzle with a simple balsamic glaze.
3. Purple Basil Butter
Compound butters are one of the easiest ways to upgrade any meal.
To make purple basil butter, soften a stick of unsalted butter, then mix in a heaping tablespoon of finely chopped purple basil leaves.
Add a pinch of salt and a squeeze of lemon juice.
Roll it into a log using plastic wrap and chill it.
You can then slice off rounds to top a grilled steak, melt over corn on the cob, or toss with hot pasta.
When you use purple basil in cooking this way, the cold butter protects the color, and the flavor infuses beautifully as it melts.
So, How Do You Use Purple Basil in Cooking?
You can use purple basil in cooking in a variety of simple and delicious ways, as long as you are mindful of the heat.
From brightening up fresh salads and making a visually stunning pesto to creating infused syrups and oils, the possibilities are endless.
While it does share a similar flavor profile with sweet basil, its bold color and slight anise-like spiciness make it a unique and wonderful addition to your culinary repertoire.
Remember that to use purple basil in cooking successfully, you should think of it as a finishing ingredient first and a cooked ingredient second.
When you embrace that rule, you’ll find that purple basil quickly becomes one of your favorite herbs to play with in the kitchen.
